Kind: research · Impact: low

## In brief

- Researchers at The Hong Kong University of Science and Technology (HKUST) report a previously unknown specialized organelle structure in a deep-sea mollusk.
- The mollusk lives at cold seeps in the South China Sea.
- The structure is dedicated to maintaining a symbiotic relationship with bacteria, and the source describes it as tiny 'dragon balls'.

## Why it matters

It describes a new cellular structure that supports a symbiosis between an animal and bacteria at cold seeps, which may matter for research on how host-microbe partnerships are organized in cells.
